Powder Coating 101
(Click Question for Answer)
What is powder coating?
Powder coating is an environmentally-friendly process that uses a solvent-free dry mix of plastic resins, pigments and fillers. The mix melts and fuses together when heated. The solid particles of coating are electrostatically charged in a spray gun and carried by low velocity air to the surface of the item. The electrostatic charge holds the powder particles in place while the part is cured in a 400-degree oven. The heat of the oven causes a chemical reaction to occur and the powder to cure, creating a highly durable finish.
What can be coated?
Any metal, aluminum or stainless steel object that can hold an electrostatic charge and withstand the heat of the curing process can be powder coated.
Is powder coating durable?
Yes. Surfaces that have been powder coated resist cracking and peeling and are abrasion, corrosion and chemical-resistant. Ask us about our testing processes to ensure quality coatings.
Is powder coating environmentally friendly?
Yes, powder coating is an environmentally friendly process. Unlike wet paint systems, the powder coating process does not use solvents in any way and VOC emissions are eliminated. With EPA regulations growing more and more specific, powder coating is quickly becoming the technology of choice. And since we have many government clients, we're held to an even higher standard than others in our industry.
What colors are available?
There is very little limitation to the colors available. In addition to standard color offerings, powder coatings are available in metallics, textures and special effects.
Is it possible for certain areas on a piece to stay coating-free?
Yes. High temperature masking and plugging can be applied to all areas not requiring powder.
What is clear powder coating?
Clear powder can be applied to a raw metal surface for those wanting a protective coat. In addition, it can be used to add a high sheen or matte finish over a colored powder and add additional UV protection.
How long does powder coating last?
While powder coat lasts significantly longer than most liquid paints, the average life span of a finished product varies depending upon the environment it is exposed to.
